成功制备了TiO2溶胶,并对其进行了N、Fe掺杂及其N与Fe共掺杂,并对其紫外光催化效果进行了研究。研究结果表明,与铁掺杂相比,氮掺杂效果不是很明显,铁掺杂效果比较明显[n(Fe):n(Ti)=0.5:100],催化效果得到有效的提高,同时铁氮共掺效果相比单掺氮有提高,但与单掺铁接近,主要来源于是掺铁的作用。 The TiO2 sol was successfully prepared, and N, Fe doping and N and Fe co-doping were carried out. The photocatalytic activity of TiO2 was studied. The results show that compared with iron doping, the effect of nitrogen doping is not obvious, and the effect of iron doping is more obvious [n (Fe): n (Ti) = 0.5: 100] The effect of nitrogen co-doping is better than that of single doping, but close to that of single doping, mainly due to the effect of iron doping.
